China just launched an unmanned cargo spacecraft. The spacecraft docked with the country's Tiangong-2 space lab.
China's first ambitious space lab, Tiangong-1 is falling back to Earth and will burn during re-entry before the end of 2017.
China's Tiangong-2, the country's second space lab, will not only serve as a space station for astronauts to perform tests in space,but it also doubles as a "luxurious" living quarters for the Chinese space crew.
China's second space lab will be launched from the Gobi dessert at 10 p.m. on Sept. 15. A manned mission will follow it next month.
